💵What this unit actually costs per month

$4,317/mo all-in
20% down at 7.4% (this week's 30-year average) · mortgage + tax + insurance + HOA
Mortgage principal & interest$2,963
Property tax (1.30% effective)$580
Insurance (estimate)$50
HOA dues$724
Total monthly$4,317
Rough cash to close$120,375

31% of that payment is not the mortgage. The HOA fee alone is $43,440 over five years — money that buys you no equity. A calculator that defaulted the fee to zero would have quoted you $3,593.

Financing type

Not FHA-approved. No 3.5%-down FHA financing on this unit, so the realistic floor is a 5%-down conventional loan ($26,750). Common for small associations and not a defect on its own, but it does remove FHA buyers from your resale pool.

Minimum realistic down payment here: 5% · verify on HUD's lookup

Rate is the Freddie Mac PMMS 30-year average for the week of 2026-10-08 — a national survey figure, not a quote. Tax, insurance and closing costs are estimates; your own Loan Estimate is the real number.
